Abstract
One-dimensional, two-dimensional and three-dimensional negative refractive index (NRI) and/or opto-magnetic materials operating in spectral ranges spanning from the visible to far IR wavelength ranges is disclosed. Said materials are comprised of metal or metal/dielectric wire pairs arranged in a number of sublattices (one for one dimensional material, two for two-dimensional and three or more for three dimensional material), such that in each lattice, said wire pairs are essentially parallel to each other. Such a materials are useful and practical in obtaining previously unachievable important optical functions in these spectral ranges. Such optical properties are highly desired for many applications. A practical means of manufacture that is compatible with cost-effective and large-scale production methods is also provided.
